Man. My bill is going to suck this month.

Turned it on that first 80* day we had a week or two ago. I feel like it's been running 24/7 since.

It's only money right?

Ive got mine set at 76 or 77 I think. Keeps my bedroom just cool enough where the fan can pick up the rest of the slack.

Our AC took a dump last week. Ordered power cap (old 50s cap finally died). Turned out fan motor died with it. Replacement is comming in today....I hope I'll get it to work and not spend a fortune on new unit. Great weather to be without AC I tell ya

My ac was on from 2pm all the way til 6am this morning.

no fucks given.

Yea that's not good. Especially if it cannot even keep up at night when it drops to low 70s.

My A/C runs a hell of a lot more than the townhouse and I feel the unit it iffy. Seems to be running all the time and temps go up sometimes while it runs. No trees, no shade, 3 story house built in 2000. I need a nest too.

I like it COOOOOLLLLLDDDD. I'll pay whatever to be comfortable.

Same here. Mine is set at 70 most of the summer.

 

[syP]

67-68 here. Always.

 

[m_dogg]

Got our unit back and running today. Set thermo to 68 after few toasty 80s days in the house.
Usually I'm between 70-72 but today is different lol

Dunno how big your home is but 109 projected is not bad with ac

Id be fine with a 100 electric bill and my place is 900 square feet... Shit was ridiculous when I had a 180 gallon reef aquarium with huge ass metal halide lights and pumps going all damn day.

New house FTW! 3800 Sq Ft, predicted bill for this month is $68. Everything is super high efficiency.

BTW, I did some research on AC units because I felt like it took awhile for mine to cool this house down and what I found was this.
-Your AC unit is made specifically for the square footage of your house.
-Your AC unit is made specifically for the environment in which you live, this is complete bull shit.

In other words, AC units installed in Chicagoland are made to work well on an average chicago summer day, AKA, low 80s. When the temps are humid and in the high 90s, your AC will have a very hard time keeping up, and that's just by some stupid design.

The sizing is calculated on a form called a manual J. AC units come in all different sizes and the appropriate one is selected based on the calculations from the manual J form. The size is then chosen for what's called a design day. 95* at 50% humidity and able to drop indoor temp 20* below ambient in our area generally. How thoroughly and accurately your contractor completes the manual J has everything to do with it.

I'm ing the reminders and that stupid graph. I'm always above all my neighbors. I think they are fucking with me!

Going from not running to turning it on, it's not unusual to take a while. Your air conditioner is better off running longer. It removes more humidity from the space which is more its purpose than strictly cooling.

Does a customer have the opportunity to say fuck that, I want an oversized unit?

Yup. People forget that the AC isn't just cooling the air in your house, it's going to have to cool down every item in your house as well, which will take a lot of time and energy.

My current bill (due in july) shows $49 due, up from 39 last cycle.

 

[Mook]

Oh, thats b/c my billing cycle just finished

My bill forecast wont be ready for a few days.

You can ask but IMO if I were the contractor I wouldn't want to put my name on it if we were doing things correctly with the calculation.

It causes other problems, like not removing humidit adequately. It's going to cool down faster no doubt but you will not be more comfortable. Also less efficient and reduced life of the condensing unit from short cycling.

 

[OffshoreDrilling]

It's no doubt tough to explain to a customer who doesn't understand the theory and operation of the system.

 

[OffshoreDrilling]

Think of it like drug dosage. Doctor prescribed a dosage for a reason and appropriately you'd hope. "But it really fucking hurts, gimme the good ones"

We had this issue with the furnace at my brothers place. The fan wasn't big enough and the burner was too big for his place so the furnace essentially cooked itself.
